Abstract
PTB provides spectral irradiance calibrations traceable to national primary standards and the SI system. A transfer standard source for high UV irradiances has been constructed and characterized. A medium pressure Hg lamp and a low pressure Hg lamp provide different spectra at different irradiance levels. The system might serve as a calibration facility for DVGW & ÖNORM conform UV sensors. Calibration by direct substitution to reference sensors can be carried out.
